WebYou take the third power, it's all going to be positive. It is all going to be positive. So this is the interval where g prime of x is greater than zero. So on which intervals is g increasing? Well, that's where g prime of x is greater than zero so it's going to be from two, from two to infinity or we could just write it like this. WebThe function h(x) h ( x) is positive if: h(x) > 0 ∴ 2x+10 > 0 h ( x) > 0 ∴ 2 x + 10 > 0. Solving the inequality leads to: 2(x+5) >0 x+5> 0 x > −5 2 ( x + 5) > 0 x + 5 > 0 x > − 5. …

[Show entire calculation] Now we want to find the intervals where f' f ′ is positive or negative. f' (x)=3 (x+3) (x-1) f ′(x) = 3(x + 3)(x − 1) WebThe rate of change would be the coefficient of x. To find that, you would use the distributive property to simplify 1.5 (x-1). Once you do, the new equation is y = 3.75 + 1.5x -1.5. Subtract 1.5 from 3.75 next to get: y = 1.5x + 2.25. Since 1.5 is the coefficient of x, 1.5 would be the rate of change. Hope that helps! forgot access code to ipad

WebThe function h is defined on the closed interval [-1, 3]. The graph of h', the derivative of h, is shown above. The graph consists of two semicircles with a common endpoint at x=1. Which of the following statements about h must be true? I. h (-1)=h (3) WebMar 8, 2024 · Solution: To find intervals of increase and decrease, you need to differentiate the function concerning x. Therefore, f’ (x) = -3x 2 + 6x. Now, taking out 3 common from the equation, we get, -3x (x – 2). To find the values of x, equate this equation to zero, we get, f' (x) = 0 ⇒ -3x (x – 2) = 0 ⇒ x = 0, or x = 2.
